mul·ti·fac·to·ri·al in·her·i·tance

inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors. Compare: galtonian inheritance.

multifactorial inheritance

the tendency to develop a physical appearance, disease, or condition that is a condition of many genetic and environmental factors, such as stature and blood pressure. See also polygene.

multifactorial inheritance

A pattern of disease inheritance which is a reflection of both environmental and hereditary factors.
 
Examples
Cardiovascular disease, cleft lip/palate, congenital heart disease, congenital hip dysplasia, type-2 diabetes, hypertension, neural tube defects, pyloric stenosis.
